COLLAR-CLASP.

Specification of Letters Patent. Patentgd N JZ E, 1919,

Application fil'ed June 26, 1919. Serial No. 307,012.

To all whom it may concern:

Be it known that I, RALPH K. MAKER, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Collar-Clasps, of which the following is a specification.

My invention relates to garment holders or clasps and is particularlyadapted to engage the opposite margins of soft turn down collars.

.The essential objects of my invention are to insure such a firm grip ofthe device upon the collar portions as to prevent accidental slipping,and without injury to the fabric; to enable the device to be used uponcollars of diilerent thickness; to enable quick assemblage of parts; andto attain these ends in an inexpenslve structure of maximum strength andfacile to operate.

To the above ends essentially my invention consists in such parts and insuch combinations of parts as fall within the scope of the appendedclaims.

In the accompanying drawings which form a part of this specification,

Figures 1 and 2, are front and plan elevations respectively of my novelholder in closed position,

3, a plan of the same in open position, I

F 1g. 4, a rear elevation of the same in closed position,

Fig. 5, a section on line 55 of Fig. 2.

Figs. 6 and 7, a plan and a rear elevation respectively of one end of mydevice with the lever and bearing member removed,

Fig. 8, a detail view of an operating memleer, and

Fig. 9, a frontelevation of my holder applied to a collar. 7

Like reference characters indicate like .parts throughout the views.

M holder comprises a bar 12 formed from a strip of flexible or resilientmetal whose ends are folded rearwardly and inwardly toward each otherforming open loops 13 and resilient or vibratory arms 14, preferablyslightly inclined forwardly to points adjacent the bar, where thematerial at the ends of the arms is bent upon itself to formsubstantially circular or closed loops 16. The

of a tubular body 21 with upset ends forming flanges 22 compressed fromcylindrical form by a punch against the opposite edges of the 100 16.

)perating members are pivotally mounted upon the bearings. Each consistsof a cam plate 24 having a peripheral cam shoulder 25 and provided witha central opening 26 to loosely fit upon its bearing member. Integralwith the cam 24 is a lever arm 28 provided with a tapering enlargement29 upon its end having a lateral shoulder or projection 30. The shoulder25 and lever arm are angularly disposed with relation to each other onthe periphery of the cam.

The operation of my device is as follows: The device is initially inopen position as shown in Fig. 3. That is to say the levers 28 are amplyspaced from their adjacent loops 14, and the cam shoulders 25 are out ofcontact with the bar 12. The lever arms are next manually presseddownwardly toward the loops 14 with the corners 32 of the collartherebetween and the enlarged lever portions 29 are snapped andmaintained gripped tightly against the loops by virtue of the camshoulders 25 which meanwhile have traveled into contact with the bar.This cam movement is freely permitted by reason of the resiliency orvibratory character of the arms 14. The resilient arms 14 cooperate withthe cam shoulders to maintain the parts in closed position as shown inFig. 2 where it will be noted that the bearing members are more remotefrom the bar 12 than is the case in Fig. 3. It will be observed furtherall the parts except the bearings 21 are stamped and cut from thin sheetmetal, and that these bearings, which are ordinary eyelets, are easilyassembled and incorporated in the structure.

I claim 1. A collar or garment clasp comprising a bar, resilientoppositely directed vibratory arms upon the same side of the bar, camspivotally supported in the adjacent ends of the 2. A collar or garmentclasp comprising a ried by the arms cooperating with the bar, lever armson the cams, and projections on the lever arms adapted to contact withresilient arms.

3. A collar or garment clasp comprising a bar, resilient oppositelydirected arms upon' the same side of the bar, lever arms pivotallysupported by the resilient arms, and means upon the lever arms engagingthe bar for lockin the lever arms against movement from t e resilientarms.

4. A- collar or. garment clas comprising a 15 bar, oppositely d rectedarms upon the same side of the bar, cams pivotally supported on theadjacent ends of the arms adapted to engage the 'bar, and lever arms onthe cams.

'In testimony whereof I have aflixed my 20 signature.

RALPH K. MAKER.
